Background and History
From what I understand, Tear gas is composed of many different gases mixed together. Reason being is that the more harsh chemical gases they add to tear gas, the more harmful it is to a persons eyes. When adding these many gasses together, the makers of tear gas have to make sure they don't add so much gas that the pressure over powers the aersol can holding the tear gas. They must find how much pressure the container can hold, and then they must make sure the amounts of gas they add all have pressures that add up to the capacity of the can.
I am now going to set up and example scenario. The calculations in this scenario won't be exact.
Say I want to mix Carbon, Hydrogen, and Nitrogen, and I want to put them in a can that holds 20 L of gas and 25 atm of pressure.
I can add 10 L of Carbon, 5 L of Hydrogen, and 5 L of Nitrogen, but if the corresponding pressure of those gases don't add up to 25 atm, it's back to the drawing boards.
